RESILIENT HEEL.

Specification of Letters Patent.

Application filed April 17, 1916. Serial No. 91,522.

- To all whom it may concern Be it known that I, JUmUs SoLoMoN a citizen of the United States, residing at ()berlin, in the county of Lorain and State of Ohio, have invented certain new and useful Improvements in Resilient Heels, of which the following is a specification.

My invention relates to improvements in resilient or cushioned heels for boots and shoes, the primary object of the invention being to provide a generally improved heel of this class which will be exceedingly simple in construction, cheap of manufacture, and efficient in use.

A further object of the invention is the provision of an improved resilient heel through the medium of similarly shaped coincidently arranged tread and chambered portions in its face and top portions, respectively, said tread portion being provided with a relatively hard reinforcing tread insert adapted to receive the initial tread of the wearer, said tread insertbeing preferably formed of metal and. suitably anchored or secured within the tread portion of the heel and being adapted to limit the movements of the latter in connection with the air cushion formed by the chambered-portion as well as to greatly prolong the life or wear of the heel as a whole.

With the above mentioned and other ends in view, the invention consists in the novel construction, arrangement, and combination of parts, hereinafter described, illustrated in some of its embodiments in the accompanying drawings, and particularly pointed out in the appended claims.

Referring to the drawings, forming a part of this specification, Figure 1, is a bottom plan view of one embodiment of the improved resilient heel, detached. Fig. 2, is a top plan view of the same, detached, showing the top or concave side thereof. Fig. 3, a side elevation of the same attached to the heel of a shoe, the air cushioning recess or chamber and the reinforcing wear receiving tread insert and stop member being shown in dotted lines. Fig. 4, a sectional view taken on line .H of Fig. 1. Fig. 5, a bottom plan view of a heel embodying a modified form of tread and chambered portion. Fig. 6, a sectional view of a modified form of tread insert. Fig. 7, a similar view of a further modified form of same.

Similar numerals of reference designate like parts throughout all the figures of the drawings.

The improved heel comprises a resilient body 1, preferably, of a suitable homogeneous molded rubber or resilient composition, said resilient heel being provided with similarly shaped coincidentally arranged tread and recess portions 2 and 3, respectively. The tread portion 2 preferably projects slightly below the plane of the face side of the resilient body 1, and may be of any suitable form or configuration, and is preferably arranged slightly to one side of the rear central portion of the heel, and the recess portion 3, is adapted to form an air cushioning chamber 3 in the top portion of the resilient heel body above the tread portion 2, and to cooperate with the latter in giving the requisite cushioning effect.

The improved resilient heel is adapted to be secured to the heel or heel-lift 4, through the medium of suitable nails or attaching elements passing through the openings 1 and through the washer members 1 in the usual and well known manner. It will be seen that the recessed portion 3, forms, conjointly with the shoe heel or lift 4;, an air chamber 3" (see Fig. 3) for cushioning the raised or projecting tread portion 2. It will also be seen that the tread and chambered portions 2, and 3, respectively, are arranged substantially concentric with each other, and if desired, the recessed or chambered portion 3, may be made somewhat larger than the tread portion 2, as indicated by dotted lines in Fig. 5, of the drawings. As a means of reinforcing the tread portion 2, as well as forming a wear receiving stop member to limit the movements of the tread portion 2, in cooperative relation to the air cushioning chamber 3, the tread portion 2, is provided 5 may come into contact with the superposed heel or heel-lift 4, upon an extended movement of the tread portion 2.

The reinforced tread insert or wear resisting element 5, is preferably provided with a shank portion 5, as shown, terminating in a headed portion 5", the latter being preferably slightly counter-sunk below the friction bearing surface of the tread portion 2, as shown most clearly in Figs. 4, 6 and 7 of the drawings. As a means of more efiectively securing or anchoring the tread-insert 5, within the tread portion of the heel, the shank portion 5, may be roughened or corrugated as at 5, as indicated in Fig. 7, of the drawings, or, if desired, the shank portion may be enlarged at its upper end as indicated in Fig. 6, of the drawings.

From the foregoing description, taken in connection with the accompanying drawings, the operation and advantages of my inven tion will be readily understood.

Having thus described some of the embodiments of my invention, what I claim and desire to secure by Letters Patent, is,-

1. A resilient heel having concentric tread and recessed portions, said tread and recessed portions having a Wear receiving metallic insert extending therebetween arranged to limit the movements of said tread portion.

2. A resilient heel having similarly shaped tread and chambered portions on opposite sides and located near one edge thereof, said tread portion being provided with a relatively hard reinforcing tread insert adapted to receive and limit the initial tread movement of said tread portion.

3. A resilient heel having an elastic projecting tread and a superposed similarly shaped air chamber, and a reinforcing metallic tread insert in said elastic tread adapted to contact with the heel and thereby limit the movements of the elastic t'read.

. 4. A resilient heel having concentric similarly shaped tread and chamber portion."

located near one edge thereof, said tread
